Revised Standard from Last Update.

1. SCOPE

1.1 This standard covers guidelines for performing low strain non-destructive integrity testing (NDT) by pulse-echo method on concrete piles covered in IS 2911 (Part 1/Sec 1) and IS 2911 (Part 1/Sec 2).

1.2 The pulse-echo method is not suitable for testing jointed precast concrete piles, steel sheet piles, H-section or hollow steel pipe piles. The method may not also determine bulges in case of under-reamed piles due to the inherent characteristics of forming of bulges in under-reamed piles in certain soils.
